Abstract
The first aim of this study is to examine whether the existence of choice of a task topic, compared to when there is no choice of topic, has a positive effect on participants’ interest (Task Interest) and self-efficacy (Task Self-efficacy) while conducting a descriptive type of task. The second aim of this paper is to examine whether the oral output of the participants (Time on Task, Accuracy, Complexity, and Fluency) while they conducted the task increased due to the implementation of choice. Data from two sessions was collected; one without and one with the choice implemented pre-task. Survey (N = 143) data elicited after the task was collected, in addition to production data collected while a smaller sample conducted the same task. Results of each collection of data were analyzed utilizing t-tests for between-subjects data. Results of the survey data indicated that Task Interest was greater for the limited choice of topic treatment than the no choice of topic treatment, but not statistically significant. Results of the production data indicated that Time on Task was significantly greater for the choice of topic treatment than for the no choice of topic treatment, possibly indicating greater intrinsic motivation when choice is available. Lastly, Complexity was significantly greater for the choice of topic treatment than for the no choice of topic treatment, possibly indicating greater complexity in the oral output of the participants when choice is available. Implications for these results are indicated for task design, task implementation, and cross-cultural psychological research.

Second language vocabulary acquisition is one of the most difficult and daunting tasks a language learner has to face. The last 30 years has seen an emergence in the importance of language learning strategies
